[Vwdiesel] injector to head leak

[Chuck Carnohan]

Loren~
I'm so glad to hear you say: "Fix the diesel leak and you won't notice
the combustion chamber leak.  :-)"
I've been experiencing the same thing with the bubbles/diesel and worry
when replacing injectors and return lines. I'm using the Semi Brake Line
material for return lines now and it has to get good and hot before it
stops oozing a bit of fuel. The minute bubbles around some of the
injectors also quits after a bit of running- or is it when the diesel is
gone to show the bubbles? We may never really know!!! I would have never
noticed the bubbles without the diesel sitting at the base of the
injector!

  I'd try removing the injector and heat shield, punker the shield back
out a tad in the middle and reseat it all.  
Re-punker the shield by setting it upside down on an appropriate socket
(OD sizes match) then punch the middle with a large center punch or such
so the middle bows back out just a tad.  
 If you're just getting a bubble or two then it most likely will seal up
in a week or so.  If you're getting diesel bubbling then most likely you
have a leak from topside and just air bubbling out around the injector.
Fix the diesel leak and you won't notice the combustion chamber leak.
